Since these RCs have a variety of types of code-models, so in order to select a suitable type of RC, one must find a type of RC from the fussy specifications and then perform the complicated operation based on the specific operation requirements described in the specification. In this way, the service efficiency of the RC decreases to a large extent. Meanwhile, for the programmer and the user, the contents and the processes are fairly complicated, and it is easy to make mistakes. In the procedure of using it, the user may come into a condition that different brands and different types of RCs cannot be produced within the same RC kernel. In this way, in order to realize the function, the user should buy corresponding URC based on the requirement, thus increasing the economic burden of the user and to be bothersome.

Furthermore, as shown in FIG. 1, there is also a learning URC in the market, whose learning method is so called “code model match”. Such type of RC highly requires the resource configuration of the hardware and is restricted by the cost of the hardware, and the costs of the hardware also increase correspondingly. Furthermore, once an original RC is lost, the code values cannot be matched. The object for the user to buy a URC is that it can be used to replace the original RC in case the original one is lost. However, the range suitable for using such RC is limited, thus, it cannot be popularized.

After the data in the RC device B60 sends the code-model, the specific data and form of the code-model is detected by the code detecting device B611, and the code-model data are transferred to the data uploading device B62 via the infrared interface B612. In the uploading device B62, it is required that the code-model data is converted into the program segments for uploading.

Please refer to FIG. 7 for the operation procedure of the entire system. Step S701 completes a step for detecting the code, the method for obtaining the code values has been described above. After the code values are obtained, the programming operation is performed in step S702, and it is tested after programming. If the testing is proved and no problem occurs after checking, then in step S704, the data are uploaded to the website. Before uploading the data, the dedicated website and the server for the RC should be provided in step S703. Before the client terminal logs on the dedicated website of the RC, the preparation for downloading should be made in step S705, for example, interfacing the USB ports of two devices, and the like. Then in the operation step S706, downloading the code program based on the instructions on the screen. After completing the downloading of the code program in step S707, in step S708, to store into E2PROM by implementing a program of MCU. In this way, in step S709, the URC can implement the corresponding function of the RC.

FIG. 8 and FIG. 9 are the procedures of the steps for the MCU kernel to process the data in the downloading processing and the data in the code sending processing. In FIG. 8, after starting the downloading of the data, the data in the code sending program are passed through the USB interface circuit in step S801, and inputted to MCU kernel in step S802 to perform the processing program for the data in step S803, and it stores the data in the code sending program into E2PROM, and saves the information addresses in step S804. In FIG. 9, when the URC is used, after the circuits are powered on and reset, firstly, the initialization is implemented internally in MCU circuit in step S901, then whether E2PROM can operate correctly or not is detected in step S902. The object of the detection is to decide whether E2PROM can perform correctly the operation of reading or writing (fixed content can be written into the specific address) before the program jumping to E2PROM. If not, then it will jump to standby, and at this time, an error indication lamp will be on. If it can operate correctly, then whether the USB port is connected or not will be detected in step S903. If it is connected, then it can perform the USB transmission operation in step S904, otherwise, whether a key is depressed or not will be detected in step S905. If a key is depressed, then the program data will be looked up in the memory based on the entry address of the key in step S906, then the code sending operation will be implemented in step S907. If no key is depressed, then whether the USB interface is connected or not will be detected in step S908. If it is connected, then the cycle will enter step S904, otherwise, then it will enter the standby state in step S909.

In the invention, the software programming associated with the hardware structure has its own features. Normally, for the conventional URC, its program calls the code data and program to perform the code sending processing, and the code data and program is disposed normally in a dedicated code data and program area. When the procedure is executed to send the code, the code data and program can be called based on the address. The USB interface data processing program, keyboard scanning program, key processing program are stored internally in such new URC, the program processing procedure is shown in FIG. 8. The data processing program mainly processes the data, which are downloaded from the network and transferred to MCU via the USB interface, transfers the data to E2PROM based on the PC pointer, processes the data transferred by the USB interface, determines whether the key code program exists on the corresponding position and performs the corresponding operation. The keyboard scanning program and the key processing program are essential parts for implementing the function of the RC, as shown in FIG. 9. When the codes are sent, the code value program in E2PROM can be read and written as required. The code value program in E2PROM is divided normally into segments each being 0.5 K, each includes a RC type. Thus, there are several separate program spaces including several types of RCs. In the key code sending program, there are a plurality of important parameters relating to the code-model, such as the data of the carrier, frequency, duty cycle, high and low voltage level for sending the code and the program for outputting the code-model. Normally, in E2PROM, each segment in ROM area is 0.5K and each segment stores one code value program, and the memory having a capacity of 16K or more can be selected as E2PROM.

In the present embodiment, the URC is the most important device in the system to realize mainly the downloading of the code value program and the function of the RC. After the code value program of the user is downloaded from the website, a procedure for filling the codes is realized. After downloading the data stream, the data are converted from the serial format to the parallel format which can be accepted by the MCU in the USB interface circuit via the USB interface protocol (The version can be updated, including V1.0, V1.1, or V2.0), and the data stream flows into the MCU via the parallel lines. A part of the data processing program is included in the MCU kernel, and it can be used to analyze and process the downloaded code value program, and to decide whether the key program exists on the corresponding position in E2PROM, then the corresponding code values are inputted to E2PROM in a DMA manner and the program is saved in the fixed positions according to the value of PC. When the user requires using the RC, after the corresponding operation key is activated, the MCU is waked up, and it will be decided by the key program to find the corresponding code value program segment in E2PROM based on the obtained PC pointer value. After finding the code value program, the code sending processing is performed by the program, in this way, the desired function of the RC can be realized.

Summing up the above, nowadays, with the development of the network, the system and method for providing the operation of the URC through the network in the invention emerge as the requirement of our times. Aiming at the specific situation of the current market of the URC, a service mode and a product are provided to allow the operation to be easier and to benefit a large numbers of users. This solves effectively the problems in the current confused market of the URC. The construction of the specific device in the above implementation method of the invention can be modified on the basis of the basic technical scheme of the invention, for example, the main function of the RC device can be realized by using single chip integrated circuit, the key panel of the RC may have different layout-designs, and the internal memory in the code detecting device and the internal devices for storing the data in the RC can be changed, and the like. The display panel of the RC can be realized by using the liquid crystal display, the panels of different types of RCs can be illuminated at different regions during the operation; the operation of the touch screen can be used to realize the operation of the RC. These do not depart the protection scope as claimed in the Claims of the invention.
